Olli-BURNING; APPARATUS.

Zb all whom it may concern Be, it known that I, CLARENCE GRANGER WHITE, a citizen of the United States, residing at Spokane, inthe; county of Spokane and State of Washington, have invented new' and useful Improvements in Oil-Burning Apparatus, of which the following is a specification.

*This invention relates to improvements in oil burning apparatus of the general type disclosed in S. Patent 791,813, issued June 6, 1905, to Jake Palmatar `It isonel of; the objects of.` this invention to provide certain. improvements whereby very: cheap andinexpensive fuell oil may be used With a high degree of thermal eiliciency, it being'possible with the device of 1 Where the heating element is subjected to the linitial or starting flame.

my? invention to: use: what is termed it topped ai i i i A; furtherV feature of this invention conwhen the element 1l is heated by the initial j or starting flame it will cause generation of sists in improved means for generating initial heat, vvhen starting the burner, to operate a steam generator and thin the oil in a very quick and efficient manner.

lOther features andnovel, parts of the invention Will be more fully 'described in connection with the accompanying drawing and will be more particularly set. forth in and by the appended claims.`

In the drawing: Figure 1 is a perspective view of a form of apparatus embodying one construction of` myinvention. Fig. 2 is a plan view thereofvvithparts in section. Fig". 3 is a sectional vienI of an oil feeding pipe. Fig. 4 is a sectional vievv of an atomizing burner head.

Like characters of` reference designate similar parts throughout the different figares ofthe drawing..

As illustrated, a support preferably in the form of a firing pan 1 is provided with standards 2 and 3 in Which a steam generator 4 is mounted. The steam generator 4 is in the form of a pipe which is closed at the right hand end thereof and which is mounted in standards 2 and 3. The left hand end of the pipe 4 is provided With any suitable form of stuffing box 5 through which an extension 6 of a Water pipe 7 projects. The Water pipe 7 is provided with a valve 8 for controlling flow therethrough. The Water pipe extension 6 in reduced in diaineter With respect to the internal diameter of pipe 4 so as to provide an intermediate space for the generation of steam. The right Specification of Letters Patent. Application filed December 23, 1912. Serial No. 738,226.

` leg 12 adjacent the discharge end 9 of pipe extension 6 may be coiled o1' spiraled, as

j indicated at 14, to increase its heat radiating surface. The remaining leg 15 extends over the pan l and may be coiled or spraled 3 as at 16 to increase its heat inductive capacity or surface adjacent to the point It Will be clear from the foregoing that steam inthe pipe 4 when water is discharged therein through extension 6. Steam is drawn off from the generator 4 through a pipe 17 which connects with a T-fitting 18 and pipe 19 which latter delivers to a A plunger valve 21 provided with a stem 22 projecting through said 'T7-fitting 18, and having a handle 23, serves to regulate the passage of the steam to the burner 20. The burner 2O is provided with an atomizing duct 24 having a flared terminal 25 from which the steam is discharged to atoinize the oil. A main fuel oil duct 26 delivers to the flared terminal 25 so that the rapidly passing or discharging steam will atomize the fuel in accordance With the well-known action of such device.

. A starting oil" duct 27 delivers abreast of the flared terminal 25 so that its discharging contents may be subjected to the action of the steam. A pipe 28 leading to the duct 27 may be connected with any suitable source of supply of oil, of the lighter type, as for instance a tank 29. An oil heating pipe 30 is connected at one end with a valvcd supply pipe 31 and is provided with a suitable stuffing or packing box $32, at its other end. A heating element, preferably in the form of a copper Wire 33 is coiled at 34 to present increased heat inductive surface to the initial flame and the Wire 33 extends through the stufling box 32 into the pipe 30 and substantially throughout the length thereof. The

Wire 33 is coiled at 35 and 36 to present an increased heat radiating surface to send the oil flowing through the pipe 30. The pipe 30 is connected by a pipe 87 to a valve 38 and the latter is connected by a pipe 39 with the burner head 20 so as to deliver to the duct 26.

By reason of the fact that the oil is heated by Wire 33, before it reaches the burner head 20, and by reason of the fact that the oil is thinned by the application of such heat I am enabled to use any kind of oil such as the heaviest Weight oils, as for instance topped oil, which latter gives a very hot flame and which is practically cheaper than any other known fuel oil. By heating the oil it not only flows freely to the burner head 20 but I am also enabled to absolutely prevent carbonization. The steam used for atomizing the oil effectively prevents soot and smoke, Which is a Waste of fuel, and which provides for an absolutely clean flame.

In the use of my invention the Water pipe maybe connected With a city main or any suitable source of supply of Water under pressure, say approximately 30 pounds. The Wires 1l and 33 are presented to the initial flame issuing from the discharge of lighter oil from duct 2T into the pan to initially heat the parts. Immediately upon heating the vvire l5 steam is generated Without the usual delay so inconvenient in cevices at present in use. By initially heating the oil, at the time that the steam is generated and by the initial Haine, I also gain appreciably, in the question of time, in starting the burner.

It Will be understood that the burner may be operated by the lighter oil iioWinO through duct 27, alone, or the heavier oii flowing thro-ugh duct 2G, alone, or the two may be jointly used Where an eXtreme-ly loiv grade of oil is supplied to duct 26.

Vhile I have herein shown and described one specific form of my invention I do not i Wish to be limited thereto except for such limitations as the claims may import.

I claim l 1. An oil burner comprising in combination, a burner head, an oil container delivering to said burner, inea-ns for delivering a Huid under pressure to said burner to discharge oil therefrom, and ametallic element having a portion thereof disposed in said container and a portion thereof lying exterior to said container and adapted to be heated to transmit heat to the oil in said container prior to its delivery to said burner, substantially as described.

2. An oil burner comprising in combination, a burner head, an oil container delivering to said burner head, means for delivering fluid under pressure to said burner to cause discharge of oil therefrom, and means disposed partly inside and partly outside of said container and adapted to have its outer vportion heated to transmit heat to the oil in said container prior to the delivery of such oil to said burner, substantially as described.

3. An oil burner comprising in combination, a firing pan,`a burner head adapted to deliver a flame over said pan, an oil chamber delivering to said burner, a steam generator delivering to said burner to cause a discharge of the oil therefrom, a Wire in and projecting from said oil chamber and having its projecting portion extended over said pan, and a Wire in and projecting from said generator and having its projecting portionV extending over said pan, projecting portions of said Wires being adapted to be heated by the starting flame from said pan, subst-antially as described.

In testimony whereof I afiiX my signature in the presence of two Witnesses.
